+This repository is the official pre-trained checkpoints for the AIGIBench in Setting-II, as described in the paper [Is Artificial Intelligence Generated Image Detection a Solved Problem?](https://huggingface.co/papers/2505.12335). These checkpoints were trained on 144K images generated by both SD-v1.4 and ProGAN, covering the same four object categories.
